When I try to load the OS X Lion Installer on my USB Stick (tried several Bootloaders, löike Chameleon old and new, chimera) I only get a kernel panic like this:

panic(cpu 0 caller 0xffffff8000548fde): "Unable to find driver for this platform: \"ACPI\".\n"@/SourceCache/xnu/xnu-1504.14.2/iokit/Kernel/IOPlatformExpert.cpp

I tried to use a matching DSDT file for my Board/Bios version, still same error.
Tried different SATA ports, just 2 GB RAM, and all kind of BIOS settings.

I can't get OS X Lion to boot the installer.

ASUS P8Z68V-Pro with latest Bios (already tried the stock one)
Just a single SSD drive connected
AHCI mode

USB3 and other settings disabled. Still I get the kernel panic.
Tried all kind of chameleon settings (like bus, pci etc.).

Anyone have inputs or tips I could use to get a working OS X Lion Install?

I've no idea if there is better way of installing Lion from scratch .. but I've used the following:


Works just fine on my setup.

  • Start with only 4GB of RAM installed
  • Disable speed step turbo in the BIOS (no other changes made to the BIOS other than drive boot order)
  • Boot from ##### Legacy
  • Put in Mac OSX CD (Wait a few seconds, press F5, select and boot from Mac OSX)
  • Install with minimal options (to save on install time if things don't work, I omitted X11 and some other things)
  • Reboot w/ ##### Legacy
  • Install 10.6.7 Combo Update (don't restart)
  • Install Bridge Helper (don't restart)
  • Install ##### options highlighted in Gordo's post with a couple modifications:
  • Use ##### instead of a custom DSDT.
  • Choose hnak's AppleIntelE1000e Ethernet instead of the one Gordo74 has selected
  • Shut down
  • Install other 4 GB of ram (8 GB total)
  • Close up case
  • Reboot and reenable speed step turbo
  • Install other stuff (X11, XCode, etc.)

I got it to work already. Made a mistake at extraxt the Lion.app to usb stick.
all is working nice now, with speed step etc.

the only thing is i can't compile my own extracted DSDT file. i get a lot of compiling errors, either in os x or windows.

will have a look with the dsdt people over in the DSDT threads.
thx anyway.
